NASA picks small spacecraft propulsion systems for development

Posted July 15, 2013 by

NASA has selected three proposals for the development of lightweight micro-thruster propulsion technologies that are small in size but have big potential. NASA’s Space Technology Mission Directorate selected the miniaturized electrospray propulsion technologies to perform stabilization, station keeping and pointing for small spacecraft. NASA hopes these technology demonstrations may lead to similar position control systems…
